thank you for that, I had forgotten that tests of the 4777 650 double pumper (wet flow) actually only yielded an actual 585 cfm, so I would have to agree with you that the 950 flows wet less than actually advertised.

go here, it is a little higher for a modified engine http://www.ajdesigner.com/phpengine/engine_equations_volumetric_efficiency.php an answer of 1 is "Therotically" right on the money" using 6000 rpm and 950 cfm for your 440 shows 1.24 which would be 24 percent too much on the flip...

Maybe he meant INCH lbs.... LOL

Ive done dozens of Holleys and never did more than 1/8 turn or so after it was seated.

The street dominator that I had years ago was all done at 5500. OK, fishmen, if I remember correctly Holley advertised this intakes maximum efficiency was from from idle to 5500, and that their design was for a mild STREET engine. Pulling past 6500 doesn't sound like a mild street engine.

Is there such a thing as a low pressure fuel injector that would work for example at 10 psi? I want to install fuel injectors in my sidepipes to add to the size of the flames coming out, and dont want to have to bear the expense of a high pressure fuel pump/fittings/hardware etc.

make sure you dont have a crossed plug wire

multiply 383 times anticipitated maximum rpm divided by 3456 if your vacuum gauge does not go to zero on wot you need a larger carb

IF you live in a cold climate I would stick with the Performer

Edelcrack or Thermoslob, the TQ giving crisp throttle response and MILEAGE

With a 3000 stall I'd be all over a double pumper. also assuming deeper gears than or 3.00 or better with a 25 inch tire or less which would effectively be about a 3.40 ratio, 3.23 would be about 3.63 and so on...

na, small wire brush on the end of a variable speed drill

Read your plugs immediately after the first nitrous pull and for the next dozen pulls if that's what it takes to dial it in. All the bench racing in the world won't tell as much as a plug that is read properly.

Due to the hood not fitting with the thermoquad adapter filter set up I Will be going with a 650 double pumper for now and need jet and power valve recommendations. Please don't tell me I need a bigger carb. this is all I have right now. 360 mag stock with a 500 cam and 286 duration should...

There's a few places to get floats, jets, gaskets. choke pull offs, etc. etc. If you need the links to the pages Ill be happy to send them. If Demon Sizzler is doing one for you it should be ready to bolt on...Good luck, I love a well tuned Thermoquad, extremely hard to beat for an all around...

Looking for ideas on a electric fuel pump mount near gas the tank. Don't really want to be able to see the pump from outside of the car. Is it really important to have the pump lower than the tank??

At this point I would tell you to start going the basics,a new set of decent plug wires, make sure you don't have a few plug wires crossed, look at all you ignition pieces carefully, do a compression test, check for things like a broken valve spring, bent pushrod etc.

9150 is 440 truck 1978. I was working at a Mopar dealership at that time and if I remember 440's in trucks did not have the lean burn. That carb should work on a mild build as it is unless some one had changed out the jets and rods.

they are only from 90-105 if that is helpful http://www.carburetion.com/Carter4TQ.htm

I still have to put it back together;. It's a 850 cfm 9077 off of a 400 lean burn a/t. I should have taken before pictures. The only thing left to do is drill a hole for vacuum for the distributor advance. Lean burn carbs didn't have ported vacuum for the dizzy, the distributor advance was...

Ok, I'm slightly confused. If I run an electric pump at 7 psi with a regulator(using an 850 thermoquad) pushing from back by the tank do I need to do anything with the return line? I was going to put a filter on the return line up by the carb and just leave the other end of the filter open??????

I have heard that for combination perfromance and gas mileage that the Avenger series is hard to beat.

I have used muratic acid in the past but found that SNO Bowl toilet cleaner as it comes mixed in the bottle will sometimes do a better job as it is dilute hydrochloric acid.

I ran a q-jet on a 327/350 horse chev motor, one of the best carbs I ever had!!

TQ, easy to find, cheap to buy and put a kit and floats in. Has an adjustable secondary air flap and adjustable secondary air flap travel setting so you can set secondaries for your particular application. Great throttle response with the small primaries. Plenty of parts still available. Here's...

Please post pics when you do. I'm also ready to do a elec. fuel pump. on my 70 Dart
